But a new report from an unannounced inspection team carried out by the CQC found evidence of sub-standard care.
Ratings for those showed one in six were ranked as poor or adequate - and the CQC warned they were risking fines or deregistration next year when the new system comes in place.
Carillion has consistently said the standard of treatment has been effective, and that it was co-operating with the CQC over its continuing inspections.
There are two main regulators - the Care Quality Commission (CQC) and Monitor.
Baroness Young, chairwoman of the CQC, admitted that the current inspection system - which the commission inherited from its predecessor - was flawed, but reforms would soon be in place.
Critics maintain that the CQC scores the wrong things and relies too much on self-reporting.
His comments follow the publication of an interim report into out-of-hours GP care by the Care Quality Commission (CQC), prompted by Mr Gray's death, which found primary care trusts may be failing to spot patient safety issues because of a lack of scrutiny.
In January this year, the Health Select Committee also expressed concern over the circumstances surrounding the registration as safety complaint of Morecambe Bay, and the CQC has hired consultants at Grant Thornton to investigate allegations of a cover-up.
In addition, people were not provided with suitable equipment to meet their needs which meant staff had to use inappropriate methods to move one person - posing a serious risk to that person and staff, the CQC said.
Gary Needle, who is in charge of assessments at the CQC, says that there will be less focus on annual snapshots and more on year-round scrutiny, as well as more attention to outcomes and patients' own experience.
The health and social care watchdog, the Care Quality Commission (CQC) has denied that it failed to take sufficient action after undercover filming showed an 80-year-old woman being assaulted by a care worker, which will be broadcast for the first time on BBC Panorama tonight.
